High level of logging being generated from storageRM when devices are in an administratively turned off state

Products

• VMware vSphere ESXi

Issue/Introduction

To make VMware administrators aware of the reason for these log messages.

Symptoms:
A high level of logging messages are generated from storageRM:

"Invalid share value: 0. Using default.” 
or
"Skipping device naa.xxxx either due to VSI read error or abnormal state" 

The level of logging will vary depending on the number of hosts in a cluster and the number of devices in an administratively turned off state.

These messages may also be classed as critical log messages within VMware vRealize Log Insight (vRLI)

Environment

VMware vSphere 7.0.x

Cause

This issue is due to devices, which are in an administratively off state (listed under "localcli storage core device detached list" ).

Since these devices will not have a SIOC share value, they are seen to have less than the min share value (200) and the log message "Invalid share value: 0. Using default.” is generated.

"Skipping device naa.xxxx either due to VSI read error or abnormal state" is generated as the device is probed and is found to be in an off state. This is not an expected state for the probe operation and therefore the log is generated.

Resolution

VMware is aware of this issue and working to resolve this in a future release.

Currently, there is no Workaround
